Jacobo Diaz has found the Tour difficult, recording 28–62 across 90 matches (31.1%). The numbers point to a player still building their Tour presence — a key area of opportunity going forward.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Jacobo Diaz has struggled at Grand Slam level: 2–11 (15.4%) in 13 matches. The best-of-five format and elite fields make this the toughest benchmark on Tour.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): a positive 6–4 (60.0%) across 10 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
vs. Top 10: 1–5 (16.7%, 6 matches). Top 10 opponents have represented a clear ceiling; addressing that deficit is the single biggest lever for improving the overall record.
By format — best-of-five: 2–11 (15.4%); best-of-three: 26–51 (33.8%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Best season: 2001 — 9–14 (39.1%) from 23 matches. The best single-season display to date — a useful reference point as the career continues to develop.
